How many miles are on the engine? If the heads have never been touched, chances are they will need attention. I think at a minimum, a proper top-end job will include new valve guides and probably new piston rings. Once its apart, you may find other things that require attention.

From what I have read, when the Turbo blows its seals, you know it because the car puts out a ton of smoke. Yours may be fine. Check for any play in the turbine shaft...you can measure with a dial indicator. There are specs in the factory service manual. If it checks out ok, run it. You can always decide later to have it rebuilt.
